Abstract

An electrolyser comprises inner tubular electrodes and outer tubular electrodes co-axially disposed to form an annular cavity through which, in use, the electrolyte flows; said tubular electrodes being disposed as a succession of tubular electrodes where a portion of the inner electrodes are inserted into a portion of the outer electrodes; wherein the polarity of the outer electrodes alternates along the flow path of the electrolyte; and the polarity of the inner electrodes alternates along the flow path of the electrolyte; the polarity of the portions of the outer electrodes is opposite to the polarity of the corresponding portions of the inner electrodes; said electrolyser further comprising an inlet for receiving pressurised fluid; an outlet allowing said fluid to exit said cavity; said electrolytes forming a serpentine path with a number of turns and lengths of tubular electrodes; electrical connections being provided between a power source and the electrolyser; further electrical connections being provided between adjacent lengths of tubular electrodes; wherein said electrolyser further comprises electrically insulating members located on the outside of said outer tubular electrodes which extend along the length of said tubular electrodes between said electrical connections.
